11-1 Functions
The functions of the EtherCAT Coupler Unit when it is used in an EtherCAT Slave Terminal are listed
below.
Function Overview Reference
Setting the Slave Terminal This function is used to read and set the Slave Terminal
parameters from the Sysmac Studio. You can make set-
tings offline, or go online and read and set the Unit con-
figuration of the actual Slave Terminal.

Slave Terminals
Cyclic I/O Refreshing The EtherCAT Coupler Unit exchanges I/O data at a fixed
interval with the mounted NX Units. There are the follow-
ing two I/O exchange methods.
• Free-Run refreshing
• Synchronous I/O refreshing
This Unit can exchange I/O data even if NX Units that
support Free-Run refreshing are mounted together with
Units that support synchronous I/O refreshing.
Section 10 I/O
Refreshing
Free-Run Refreshing The timing at which the EtherCAT Coupler Unit
exchanges I/O data with the mounted NX Units is asyn-
chronous with the timing at which the NX Units refresh
the data to be exchanged.
Synchronous I/O
Refreshing
The timing at which the EtherCAT Coupler Unit
exchanges I/O data with NX Units that have the functions
listed below is synchronous with the timing at which the
NX Units refresh the data to be exchanged.
• Synchronous input refreshing
• Synchronous output refreshing
NX Unit Mounting Settings This function is used to register NX Units that are not
connected to the actual configuration but will be added at
a later time in the Unit configuration information as
unmounted Units. If you use this function, you do not
have to modify the user program after the NX Units are
added.

Troubleshooting with
Error Notification through
Sysmac Error Status
This function allows the EtherCAT Coupler Unit to use the
Sysmac error status, which is assignable to I/O data, to
notify the EtherCAT master when an error occurs. This
notification acts as a trigger that allows you to use the
troubleshooting functions on the Sysmac Studio to view
and correct errors that occur in the EtherCAT Slave Ter-
minal.
Saving Node Address
Settings
This function sets the node address on the Sysmac Stu-
dio.
Verifying the EtherCAT
Network Configuration
Using Serial Numbers
This function verifies the EtherCAT network configuration
based on serial numbers.
SII Data Checking The EtherCAT Coupler Unit checks the information in the
SII (Slave Information Interface).
